Description

A hearty, meaty, cheesy slow‑cooker spaghetti that’s easy to prep—just brown the beef, combine ingredients in your crockpot, and let it do the work for a comforting dinner.


Ingredients

  • 1 tablespoon olive oil
  • 1 pound lean ground beef
  • ½ cup diced yellow onion
  • 1 tablespoon minced garlic
  • 2 teaspoons Italian seasoning blend
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • 1 pound standard spaghetti noodles, broken in half
  • 48 ounces (2 24‑ounce jars) tomato & basil marinara sauce
  • 15 ounces crushed tomatoes
  • 2 cups chicken broth, divided
  • ½ cup grated Parmesan cheese
  • 1½ cups shredded mozzarella cheese
  • 1 tablespoon chopped fresh parsley (optional garnish)

Instructions

  1. In a skillet over medium‑high heat, add the olive oil, lean ground beef, diced onion, minced garlic, Italian seasoning, salt, and pepper. Cook and brown the beef until no pink remains; drain excess fat if needed.
  2. Add the cooked beef, broken spaghetti, marinara sauce, crushed tomatoes, and 1 cup of chicken broth into the crockpot.
  3. Cover and cook on HIGH for 2 hours or until the noodles are tender (watch carefully to avoid overcooking).
  4. Remove the lid, stir in the remaining 1 cup of chicken broth, then top with Parmesan and mozzarella cheeses.
  5. Replace lid and cook for another 20–30 minutes, until the cheese has melted.
  6. Sprinkle with chopped fresh parsley, if desired. Serve immediately.

Notes

  • Cook time: 2½ hours on HIGH (or 3½–4 hours on LOW).
  • Yields approximately 8 servings (about 1 cup per serving).
  • Storage: Refrigerate leftovers in an airtight container for up to 3 days.
  • Freezing is not recommended—the noodles absorb too much sauce and texture changes upon thawing.
  • Reheat individual portions in the microwave for about 1–1½ minutes, or per your microwave’s instructions.
  • Serve immediately—noodles continue absorbing liquid and get softer the longer they sit.
  • Substitute water for chicken broth if needed; low‑sodium broth works too.
  • Add a pinch (¼ teaspoon) of red pepper flakes for a touch of heat.
  • “Pot‑sized” spaghetti noodles (e.g. Mueller’s) can be used without breaking—they fit well and reduce uneven pieces.
